Suppose the derivative of a function fis Then f(x) is decreasing on the following interval: O (-1,00) O(-∞, -3) O(-3,-1) O(-∞, -1) f'(x) = (x+3)(x - 2)²(x + 1)³. O (-1,2) 馬
Suppose the derivative of a function f is
f'=x+3x-2x+13
Then f is decreasing on the following interval:
O1,0
O-00-3
O-3,-1
O-00-1
O-1,2
